Webb said the woman's Texas driver's license listed an address in Irving.

Next of kin was notified, he said, but family members said they had not seen Descoteau in more than a decade.

Descoteau was not a drifter, the investigator said, adding she held a commercial driver's license.

"She worked. She had jobs," he said.

It was not clear if she was employed as a truck driver at the time of her death.

Because the victim was unclothed from the waist down, authorities have said they suspect she may have been sexually assaulted.

Two truck drivers travelling cross country discovered Descoteau's body about eight feet off the access road when they stopped at midday to check their tires near the FM 450 ramp onto Interstate 20 south of Hallsville.

At first, they said, they thought the body was a mannequin on the roadside. Investigators said the victim had been at the location no more than 12 hours.

Investigators are asking anyone who may have had any contact with or seen Descoteau at any location, to contact the Harrison County Sheriff's Office. All information will be considered confidential or information may be given anonymously to Crimestoppers at (903) 935-9969.
